Which consequence results when a lens coating cracks?

💡 Explanation

Cracks introduce phase shifts in reflected light, leading to localized variations in thin-film interference. Because there are additional uncontrolled reflections at the cracks, enhanced destructive interference will darken those areas, therefore reflection increases from the defect rather than uniform low scattering.
